battery size /group??

Try the battery lookup at Interstate. You can also check the Costco site which has great battery prices.

Optima Batteries. They have a place on their website to advise you on the size for your vehicle. Unfortunately depending on where you live batteries sometimes only last for 3 years due to weather conditions.

ok thanks

Walmart by the batteries should have a little computer screen where you can put the information on your car into and it will tell you the group size for it (also slightly cheaper than a parts store if short on cash)
